Nice logic on the mage nerf
You say AP items were "too gold efficient". News flash: the game was already balanced around that! If you are going to nerf every single AP item AND severely buff the major mr items, you need to buff the mages to keep the game balanced. Honestly, does someone at riot just loathe AP champions? Why not just remove them all from the game, and just keep physical and true damage. Until the next patch when this gets fixed, the game is going to revolve around AD mid and then who gets to pick corki.
I wish you had some sort of internal review/check system so that these really stupid ideas never make it to the live game.
